DMABUFs are all handled by videobuf2, so there is no reason not to enable support for them. Note that this driver is still using the vmalloc allocator, so the buffers it allocates will not be compatible with the codec or ISP driver that require contiguous buffers. However this driver should be able to import the buffers allocated by them. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
